Application overview
The Flashlink hdSdi-Cho-2x1 is a multi bit-rate change-
over providing intelligent input switching in studio and
broadcast applications.
The unit provides the ability to change between inputs
based on input signal integrity.
The inputs are protected with bypass relays that ensure
passive loop-thru of both input signals to their respective
outputs in case of mains or card failure.

Product description
The Flashlink hdSdi-Cho-2x1 is a serial digital video
2x1 change-over module providing high performance line
protection for various signal formats from 1Mbps up to
1485Mbps. The unit can be configured to perform cable
equalizing and re-clocking of SMPTe 292M, SMPTe
259M and dvB-ASi signal formats. The switching criteria
can be selected to be based on loss of input signal or
loss of lock (re-clocker). The switch can either be latching
or non-latching (in loss of lock mode, only latching switch
is available). it is also possible to control the switch with
GPi inputs, with the GYdA system controller or with the
open protocol rS422 interface.
The two inputs typically provide automatic cable
equalizers for up to 250 meters of cable (Belden 8281A
at 270Mbps) with a 2 x 1 switch in front of a re-clocker
with 4 outputs. The re-clocker supports the bit-rates;
143, 177, 270, 360, 540 and 1485Mbps. For other rates,
the re-clocker automatically switches to bypass mode
and the hdSdi-Cho-2x1 will work as a non-reclocking
2x1 change-over unit with cable equalizer. The hdSdi-
Cho-2x1 also has a special dvB-ASi mode, enabling
all possible rates including empty transport streams with
only K28.5 padding packets. 2 outputs are non-inverting
to support dvB-ASi compatibility.
The hdSdi-Cho-2x1 is designed for various line
protection applications for studio, campus, broadcast and
telecom.
